Denver Broncos liking their defensive makeover

(Eds: APNewsNow. With AP Photos.) By ARNIE STAPLETON AP Pro Football Writer The Denver Broncos like how their defensive makeover is going even though nose tackle Ty Warren was on the operating table Tuesday instead of the football field. Warren was supposed to be the centerpiece of the refurbishing, the anchor of John Fox's 4-3 defense. But he tore his right triceps during practice last week and underwent surgery that will sideline him at least until November and possibly for the whole season. They'll get tackle Marcus Thomas back from a torn chest muscle next month. For now, Brodrick Bunkley and Kevin Vickerson are the starting run-stuffers. The Broncos are making strides in the secondary and on the edge thanks to rookies Von Miller and Rahim Moore and the return of 2009 NFL sacks king Elvis Dumervil.
